Ephapsys helps you empower and govern AI agents.

Ephapsys SDK

Lightweight SDK for EC-ANN modulation, trusted agent provisioning, and runtime security.

---

📦 Installation

pip install ephapsys

Optional feature groups:

pip install "ephapsys[modulation]"
pip install "ephapsys[audio]"
pip install "ephapsys[eval]"
pip install "ephapsys[vision]"      # alias: [video]
pip install "ephapsys[all]"

Choose the profile by workload:

Workload	Install command
Lightweight orchestrator/proxy only	pip install ephapsys
Agent runtime (HelloWorld language)	pip install "ephapsys[modulation]"
Agent runtime (Robot multimodal)	pip install "ephapsys[modulation,audio,vision,embedding]" + pip install webrtcvad sounddevice pyaudio
Modulators/training scripts	pip install "ephapsys[modulation]"
Modulators with full evaluation/report stack	pip install "ephapsys[all]"

---

🚀 Quickstart

from ephapsys import TrustedAgent

agent = TrustedAgent.from_env()

ok, report = agent.verify()
if not ok:
    raise RuntimeError(f"Agent blocked: {report}")

agent.prepare_runtime()
print(agent.run("Hello world", model_kind="language"))

⚙️ Environment Variables

Variable	Description
EPHAPSYS_AGENT_ID	Agent ID/label assigned by AOC
AOC_BASE_URL	API endpoint, e.g. http://localhost:8000
AOC_ORG_ID	Org identifier (non-secret tenant scope)
AOC_PROVISIONING_TOKEN	Provisioning credential exchanged for short-lived device token
EPHAPSYS_STORAGE_DIR	Optional, defaults to .ephapsys_state

For edge production, use hardware anchors (tpm, tee, dsim, hsm) and avoid PERSONALIZE_ANCHOR=none.

---

🎛️ ModulatorClient

Start / iterate / complete modulation on model templates:

from ephapsys.modulation import ModulatorClient

mod = ModulatorClient(api_base="http://localhost:7001", api_key="dev")
resp = mod.start_job(
    model_template_id="google/gemma-2b",
    variant="ec-ann",
    search_space={"lr": [1e-3, 1e-4]},
    kpi={"accuracy": "max"},
    mode="auto"
)
print(resp)

---

🖥️ CLI

The SDK includes a CLI (ephapsys) for working with agents, models, modulation, and certificates.
Authentication is required before most commands.
